We always have to be on guard against alien invaders, but generally Holderness and East Yorkshire is something of a safe haven for many of our native plants who exist in waterways and meadows thankfully free of invasive species.
This is partly thanks to the geology of the area with the dry peaks of the Yorkshire Wolds barring the transit of many riverine species. So far the Wolds have seemingly deflected the muntjac deer which will be the next great menace to woodland flora, having already ravaged much of Norfolk’s best hazel coppice and nightingale thicket. Muntjac have reached Scarborough now but have not as yet been logged east of the Wolds.
We still have the issue of American mink which are a hang-over of long closed fur farms – this year the scourge of water voles made a new offensive in the northern River Hull and we’re now dealing with the fallout here at Yorkshire Water’s Tophill Low Nature Reserve. After a spate of sightings thankfully post breeding season volunteers are currently running ten ‘mink rafts’ in an effort to get them before they get the voles.
